Taipei 101 is tall and was the tallest building in the world from 2004 to 2009. As of 2026, it is the
eleventh-largest skyscraper in the world and the tallest building in Taiwan. It was last climbed by
Alain Robert in 2004, over the course of four hours in heavy rain and with a safety rope, meaning it was not a
free solo climb. Robert, who has climbed about 200 such buildings, rates it at 6 out of 10 on his difficulty scale. Honnold became famous in 2017 for his free solo climb of the
El Capitan rock formation in
Yosemite National Park, which was the subject of the Academy Award-winning documentary
Free Solo. His climb of Taipei 101 was his first significant climb of a man-made structure. Honnold was 40 years old during this climb. He practiced climbing portions of the building to prepare for the live ascent, telling
The New York Times that he climbed it with ropes "two or three" times. In advance of his climb, Honnold participated in a traditional Taiwanese blessing ceremony to pray for success. == Broadcast ==
